Lamprophyres (grecki λαμπρός (lamprós) = "jasny" i φύρω (phÝro) = do mieszania) są rzadkie, małe objętościowe ultrapasożytnicze skały zapalne głównie występujące jako bagna, lopolit, lakcolity, zapasy i małe włamania. Są to alkaliczne krzemionkowe nienasycone skały mafickie lub ultramaficzne o wysokim tlenku magnezu,\u003e 3% tlenek potasu, wysoki tlenek sodu i wysoki nikiel i chrom. Lamprophyres występuje we wszystkich epokach geologicznych. Przykłady Archaea są powszechnie związane z depozytami złota litego. Przykłady kenozoiku obejmują skały magnezowe w Meksyku i Ameryce Południowej oraz młode lampowe lampy z Gympie w Australii z 18,5% MgO przy 250 Ma.
